how to modify

I have just found Bibword and Bibstyles and I think it is an interesting tool.

I would like to know how can I slighlty change some features of a Style (namely, Harvard).

I see that when I insert a citation in the text body, it is always within round brackets: this is ok when the citation is in the text, but it is not ok when it goes into a foot-note (at the beginning of a foot-note). So, I would like to change the
code in order to never get automatically the parentheses.

The question is: how can I modify the code?

Beside, I do not understand how use BibWord. I have downloaded the guide but I do not understand its use.

A BibWord stylesheet groups all formatting info into a single place inside the XSL file: the
data variable. So to find out where things are stored, just look for

<xsl:variablename="data">

In it there are a number of child elements defining the behaviour for certain sections. You might want to look to the
citation element. Two elements are of importance to you.: openbracket and
closebracket. By keeping those elements empty, no surrounding brackets will be shown around (grouped) in-text citations.

Note thqt Word 2007 does not know the difference between in-text citations and footnote citations while Word 2008 for Mac does. In the latter case, you probably shouldn't change the brackets of the
citation element but rather of the footnotecitation element.
